Details
Meanwell LPF-25-54 is 25W AC/DC LED driver with 54V29.7-54V0.47A25.38W350mVp-p±4.0%±0.5%±0.5%. The product highlights the dual modes constant voltage and constant current output. Meanwhile, it can operate from 90~305VAC with rated voltage 54V. Since the efficiency reaches high up to 87% based on fanless design, LPF-25-54 is able to work for -35°C ~ +70°C case temperature through free air convection. In addition, it is rated with IP67 ingress protection level. Thanks to its longevity, high reliability and excellent quality, Meanwell LPF-25-54 is suitable to work for a variety of applications at dry, damp or wet locations.
